[QUOTE="Goldpick, post: 431084, member: 1695"] What did you use as a power source for the electrolysis, sounds like it was a bit too powerful for the job at hand? In the past I just used any old phone charger or 9v power source lying around, doesn't take much power to get the process happening, and usually only takes a few minutes to loosen up any oxidation. Just use an old bolt or nail for the positive lead and the coin with go onto the negative lead - for the liquid I just use a water and salt mix. Also keep the positive cable and clip out of the solution to prevent copper from being transferred to the coin, also do not use stainless steel due to the dangerous by-products created from the chemical reaction. :) [/QUOTE]
